TIE WIRE WITH DEF-SRMED nuns.

Original application filed November 18, 1920, Serial No. 424,884. Divided and this application filed June 14, 1922. Serial No. 568,303.

To all whom it may concern:

Be it known that we, Arno J. GERRARD and PARVIN WRIGHT, respectively a subject of the King of Great Britain and a citizen of the United States, both residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tie Wires with Deformed Ends; and we do hereby declare the follow- 1 ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bale ties or tie spires having deformed ends, especially adapted for use in connection with that type of wire tyin machines disclosed in our copending app ication #525,903, filed December 31,1921, and entitled Wire tying machines. It has for ts object to provide a tie wire which will be simple in construction, comparativel inexpensive to manufacture, and more e cient in use than those which have been heretoiore proposed.

With these and other objects in view, the invention consists in too novel details of construction and combinations of parts constituting the tie wire, all as will be more fully hereinafter disclosed and particularly point ed out in the claims. 1

This case is a division of our copending application Serial No. 424,884, filed November 18, 1920, for wire tying machines.

Reierring to the accompanyin drawings forming a part of this speci cation, in which like numerals designate like parts in all the views;

Figure l is a digrammatic elevational view of amachine adapted to use these particular tie wires;

Figure 2 is a side elevational view of one of the holding posts employed in said ma Figure 7 is a view of a tie wire having both of its ends deformed.

In order that the invention may be the more clearly understood, it is said: There has recently been developed the type of wire tying machines illustrated in Figure 1, which puts two parallel bights of the tie wire under tension, after it has seen wrapped around a box, and then while these bights are under a considerable strain, the said machine twists them together into a knot. It is desirable that the ends of the wires used in these particular machines be deformed, as illustrated in he drawings, for the deformation of said ends affords a number of advantages in the ractical use of the machines, which can ony be appreciated from a general knowledge of the construction and operation of the'machine, and such operation and construction may be understood from what follows:

As is more fully disclosed in our copending application above mentioned, 1 indicates the framework 'of the machine especially adapted to employ these tie wires, 2 a holding post for one end of the tie wire, 3 a housing enclosing a twisting mechanism adapted to twist together parallel bights of the tie wire, t a second holding post surrounded by a cutter 5 for cutting oft one of the bights after the twisting operation, 6 a means for putting a tension on the tie wires before the twisting operation, 7 a means for operating the tensioning means 6, and 8 represents a package around which the tie wire is passed prior to thetensioning, twistindg and cutting operations. The machine is a apted to rest upon the top of the package 8, and a deformed end 9 of the tie wire 12 being inserted in the post 2, while the other end 13 of said wire is secured to the ratchet 6, an operation of the lever 7 wiil put a very considerable tension on the parallel bights 10 and 11 of the wire, while an operation of the handle 14: will cause said bights when still under tension to be twisted together, as illustrated in Figure 6.

Now, if no deformation of tie wire end were provided, as is illustrated by the meral 9, some other means wouid have to be employed to hold the wire securely place, and said means would not oniy have to secureiy hold said during the am: new

sioning operation, but it would also have to enable one to readily introduce the wire into the machine before the twisting operation and to as readilyremove it after said operation. Such holding devices, however, have in all cases heretofore been found to be very slow when operating them in practice, and they have also been found to be objectionable in that they usually bite into the wire when under the heavy strains employed, and thus are the wires liable to be broken or pulled loose. On the other hand, by employing a deformed end, for the tie wire, such, for example, as the corrugations in the end 9, one is enabled to seize said end 9 with his left hand, to slip it into the post 2, as indicated, and his right hand being free, he can at the same time entrain the wire 12 around the package 8' and bring its bight 10 back through the slot in the holding post 2 and through the slot in the hold-' ing post 4;, and carry said bight 10 around the'ratchet fi and secure its end 13 in a'notch in said ratchet, all in an incredibly short time.

After this is done, the tensioning and twisting operations take place, as above mentioned, and they are completed in a few seconds, whereupon the cutting edge 22 automatically cuts off the bight 11 and [tucks it down beside the main body portion of the bight 10 of the wire. Thus 'is the said severed end prevented from sticking up andforming a snag to tear the ends of those handling the package 8 or to rip open superposed packages which are moved over the package 8.

In making these tie wires, it isconvenient to provide both ends with corrugated deformed portions 29, as illustrated in Figure 7, for when small packages are banded, there is a considerable waste portion severed by the cutter 5, and this severed end being provided with the deformed portion 20, it may be used itself as a tie wire on a small package.

.It will thus be'seen that any given corrugation constitutes a depression or a recessed portion on one side of the wire, and a holding abutment on the other side of the wire, which coact with complemental parts in the holding post 2, to prevent endwise I movement of the wire when put under ten- It'is obvious that those skilled in the art may varythe details of construction of this tie wire without departing from the spirit of the invention, and therefore it is not desired to be limited to the above disclosure exciapt as may be required by the claims. hat we 0 aim is:

1. Asa new article of manufacture a tie wire adapted for use in wire tying machines and provided with a deformed end having a plurality of bends of the same cross section as the main body portion of the wires, substantially as described.

2. As a new article of manufacture a tie wire adapted for use in wire tying machines and provided with a deformed end of the same cross section as the main body portion of the wire, and having a plurality of with a plurality of angularly disposed hold- 7 ing portions, substantially as described.

'5. As a new article of manufacture a tie wire adapted for use in wire tying machines provided with a deformed end having a plurality of corrugations, substantially as described. I

6. As a newart icle of manufacture a tie wire adapted for train wire tying machines and provided with a'deformed end of the same cross section as the main body portion of the wire and having two parallel portions of said wire twisted into a knot, substantially as described.

A wire package binder of uniform cross section provided with a recess and a shoull'd'ered portion adjacent an end andproducing an abutment to prevent endwise move ment of the binder when put under tension.

8. As a new article a wire package binder of uniform cross section preformed to produce a recess and an abutment to prevent endwise slipping of the binder when put under tension. 7

9. As a new article a wire package binder of uniform cross section having a portion adjacent an end deflected out of the plane of the wire and producing a recess and an abutment to serve with a coacting abutment to prevent endwise slipping of the binder when the latter is placed under tension.

10. A wire package binder of uniform cross section formed intermediate its ends with an abutting shoulder, the portion of the wire forming said shoulder being offset from the median line of the wire with the end of the wire extended freely beyond said shoulder.

11. A wire package binder of a uniform cross section recessed adjacent an end portion and producing a shoulder-adapted to resist slipping when tension is applied thereto.

12. A package binder of a uniform cross section comprising alength of Wire deflected adjacent an end portion thereof and producing a shoulder adapted to resist slipping when tension is applied thereto, one end portion of the wire extending freely for an appreciable distance beyond said shoulder.

13. A Wire package binder of a uniform cross section deflected at a point adjacent an end portion and provided with a plurality of shoulders separated by an intervening space, said shoulders operating to prevent slipping when tension is applied to the wire.

In testimony whereof We afiix our signatures.
